Access 2010 form question

I haven't used in Access in quite some time so I am a little rusty, and never used 2010 version. I have a form. On the form I have 2 drop downs and 2 text boxes. User picks a value from the first drop down, that runs a query and populates the second drop down. The second drop down the user selects a vendor. After that the ID value of the vendor is put into one of the text boxes that is hidden. What I need to do in addition to that is run a query using that value to populate the other text box. I have tried refreshes on the drop down change and on the hidden text box change but that other textbox just remains blank. Any help is appreciated.

Try the AfterUpdate event of the 2nd dropdown.

Which is the "other textbox"? The hidden one with the ID, or another?

Also, you may find it works better to store the ID value in a custom database property, from which it can be retrieved throughout the database. Here is some sample code:

Option Compare Database
Option Explicit

Private dbs As DAO.Database
Private prp As DAO.Property
Private prps As DAO.Properties
Private strPropertyName As String
Private strPropertyValue As String
Private lngDataType as Long
Private varPropertyValue As Variant


Public Sub SetProperty(strName As String, lngType As Long, _
   varValue As Variant)
'Created by Helen Feddema 2-Oct-2006
'Modified by Helen Feddema 2-Oct-2006
'Called from various procedures

On Error GoTo ErrorHandler

   'Attempt to set the specified property
   Set dbs = CurrentDb
   Set prps = dbs.Properties
   prps(strName) = varValue

ErrorHandlerExit:
   Exit Sub

ErrorHandler:
    If Err.Number = 3270 Then
      'The property was not found; create it
      Set prp = dbs.CreateProperty(Name:=strName, _
         Type:=lngType, Value:=varValue)
      dbs.Properties.Append prp
      Resume Next
   Else
   MsgBox "Error No: " & Err.Number _
      & " in SetProperty procedure; " _
      & "Description: " & Err.Description
      Resume ErrorHandlerExit
   End If

End Sub

Public Function GetProperty(strName As String, strDefault As String) _
   As Variant
'Created by Helen Feddema 2-Oct-2006
'Modified by Helen Feddema 2-Oct-2006
'Called from various procedures

On Error GoTo ErrorHandler
   
   'Attempt to get the value of the specified property
   Set dbs = CurrentDb
   GetProperty = dbs.Properties(strName).Value

ErrorHandlerExit:
   Exit Function

ErrorHandler:
   If Err.Number = 3270 Then
      'The property was not found; use default value
      GetProperty = strDefault
      Resume Next
   Else
      MsgBox "Error No: " & Err.Number _
         & " in GetProperty procedure; " _
         & "Description: " & Err.Description
      Resume ErrorHandlerExit
   End If

End Function

Public Function ListCustomProps()
'Created by Helen Feddema 3-Oct-2006
'Modified by Helen Feddema 3-Oct-2006
'Lists DB properties created in code (as well as built-in properties)

On Error Resume Next
   
   Set dbs = CurrentDb
   Debug.Print "Database properties:"
   
   For Each prp In dbs.Properties
      Debug.Print vbTab & prp.Name & ": " & prp.Value
   Next prp

End Function

==================================
Usage examples:

Private dbs As DAO.Database
Private prp As DAO.Property
Private prps As DAO.Properties
Private lngDataType As Long
Private strPropertyName As String
Private strPropertyValue as String
Private varPropertyValue As Variant

Date
====
   strPropertyName = "PropName"
   lngDataType = dbDate
   Call SetProperty(strPropertyName, lngDataType, dteStart)

   GetStartDate = CDate(GetProperty("PropName", ""))

Text
====
   strPropertyName = "PropName"
   strPropertyValue = CStr(cbo.Value)
   lngDataType = dbText
   Call SetProperty(strPropertyName, lngDataType, _
      strPropertyValue )

   strDocsPath = GetProperty("PropName", "")

Long
====
   strPropertyName = "PropName"
   lngDataType = dbLong
   Call SetProperty(strPropertyName, lngDataType, lngID)

   lngID = CLng(GetProperty("PropName", ""))

Integer
=======
   strPropertyName = "PropName"
   lngDataType = dbInteger
   Call SetProperty(strPropertyName, lngDataType, intMonth)

   intID = CInt(GetProperty("PropName", ""))

Saving to a custom property from a control's AfterUpdate event
==============================================================
Private Sub txtDate_AfterUpdate()
'Created by Helen Feddema 2-Sep-2009
'Last modified 2-Sep-2009

On Error GoTo ErrorHandler
   
   If IsDate(Me![txtDate].Value) = True Then
      dteSingle = CDate(Me![txtDate].Value)
      strPropertyName = "SingleDate"
      Call SetProperty(strName:=strPropertyName, _
         lngType:=dbDate, varValue:=dteSingle)
   End If
   
ErrorHandlerExit:
   Exit Sub

ErrorHandler:
   MsgBox "Error No: " & Err.Number & "; Description: " & _
      Err.Description
   Resume ErrorHandlerExit

End Sub

On AfterUpdate I tied to embed a macro that does a requery on that control and it doesn't do anything. Should I be doing something else?
